Description

[Detailed description of the invention] This invention relates to a fish signal device, in which a modulated wave transmitted from a float is received by a receiver placed near the angler, and the notification section is activated only when there is no modulated signal. Depending on the circuit,
When waiting for fishing, the alarm unit is stopped, and when a fish pulls a float into the water, the alarm unit is activated to notify the angler of the fish, taking advantage of the characteristic that radio waves are greatly absorbed and attenuated underwater. The purpose is to obtain equipment.

Conventionally, there is a radio-controlled float that transmits radio waves by operating a switch and generates a sound to inform a receiver placed near the angler. When the float is pulled into the water, the radio waves are absorbed and attenuated by the water, so the sound from the receiver stops.Therefore, the receiver only makes sound when the float is pulled into the water after there is a fish signal. If the fish pulls in the float while the float is submerged in the water due to waves, etc., no sound will be produced, and as a result, even if the point is fixed, the fish will not be able to catch the fish. There was the inconvenience of not having faith.

The present invention eliminates these drawbacks and provides a reliable fish tracking device.The present invention will be described below with reference to drawings showing embodiments thereof.

1 to 3, reference numerals 1 and 1' denote a float main body that is configured to be able to be separated into upper and lower parts, and a battery 2 is installed inside the float main body 1, and this battery 2 is inserted through a battery holder 3. , is connected to an electronic circuit 6 consisting of a transmitting section 4 and a modulating section 5.

The transmitter 4 radiates radio waves to the outside using an antenna 7 attached to the top of the float body 1.

Furthermore, since the modulator 5 provides a modulated signal to the transmitter 4, the radio waves radiated from the antenna 7 become modulated waves.

Further, the frequency is adjusted by turning the adjustment core 8.

9 is a general receiver such as an FM-AM radio, and this receiver 9 receives radio waves radiated from the float and outputs a modulated signal.

10 is an adapter according to the present invention; 11 is a filter that passes only the modulated signal emitted from the float; noise generated by the receiver 9 is cut by this filter 11.

In addition, the input terminal of the filter 11 is the output terminal of the receiver 9 (
You can easily connect it by simply connecting it to an earbon terminal, etc.

12 is an inverting circuit, and this inverting circuit 12 is the filter 11.
After detecting the output of the filter 11, the notification unit 13 is stopped and the float is pulled into the water, and the filter 11
When the modulation signal weakens (or disappears), the notification unit 13
It operates in reverse.

Further, the notification section 13 receives a signal from the inverting circuit 12, and uses the speaker 14 to notify the angler 6 (= fish catch), but other visual notifications such as a bean ball are also possible.

As described above, the present invention determines the state in which the float is drawn into the water based on the strength of the radio waves, so the fish report will match the state of the float, and as a result, it will be possible to know the reliable fish report. be able to.

Furthermore, since there is no switch mechanism or the like inside the float, the structure is simple and reliability is improved.

Furthermore, by using f modulated waves, a general receiver can be used, and it can also be used in combination with a noise filter, making it resistant to noise and easy to detect over long distances. ” By simply adding the following information, anglers can be notified of fish alerts using an easy-to-understand notification sound.
